Seems to be a good enough deal, get it! But I would not get four of the, but yeah, I do not know your financial state so....

I want RAID 0 performance and then mirroring. So Raid 10. hence 4 of em. I paid 80 for my WD 2TB greens. So yes, about 20 bucks more per TB, but also those drives were much slower and much higher fail rate. So I don't see it as much of a difference.
